Need help

In Minecraft every time i join my server i take 8 steps or so then i freeze for 15 seconds-ish then i can keep going for 7 steps... i was playing yesterday fluently but at night it started happening, i didn't mod any of my folders, i play on a cracked version.

Try multiple clients/versions, and report back if there's any difference.

maybe ur av suddenly started scanning your pc or something?

try play on another server and look if it is any difference
